Abstract
The utility model provides an elevator steel wire rope tensioning device comprising a tensioning box and a main box body. Guide rails allowing the tensioning box to slide up and down on the main box body are arranged on the two sides of the tensioning box; a tensioning wheel is arranged in the tensioning box and is connected with the tensioning box through fixing shafts on the two sides; a clamping groove allowing a steel wire rope to pass is formed in the tensioning wheel; the two sides of the main box body are provided with installing holes; a balance weight chamber is arranged in the main box body and is connected with the tensioning box; the lower portion of the main box body is provided with a limit switch and a limiter; the limit switch and the limiter are electrically connected; a plurality of movable balancing weights are arranged in the balance weight chamber; and a clamping buckle for preventing separation of the tensioning box is arranged on the main box body. The elevator steel wire rope tensioning device is simple in structure and convenient to use. With the limiter and the limit switch, the elevator steel wire rope tensioning device can guarantee the safety of an elevator during running of the elevator and thus guarantee the safety of passengers in the elevator.
Description
Technical field
The utility model relates to a kind of steel rope take-up device, particularly relates to a kind of elevator wire rope swelling device.
Background technology
Skyscraper is more and more now, also more and more higher, this requirement for elevator is also more and more higher, require fast, low noise, safe and reliable, be indispensable critical component as the swelling device using on senior express elevator, so have a high-efficient noise-reducing to this, the swelling device that adjustable is strong will have very large demand and room for promotion.Existing steel rope take-up device just plays effect fixing and that slow down mostly, but once fracture occurs the take-up device on elevator will threaten to the life security of the passenger in elevator.Therefore, be necessary existing steel rope take-up device to improve, make it can be by increase a limiting device and limit switch on swelling device, thereby ensure the safety of elevator in the time of operation, and then ensured the safety of passenger in elevator.
Utility model content
In order to overcome the weak point of existing steel rope take-up device, the utility model provides a kind of elevator wire rope swelling device.
The technical solution of the utility model is achieved in that
A kind of elevator wire rope swelling device of this programme, comprises tensioner case and main box, and the both sides of described tensioner case are provided with for its guide rail sliding up and down on main box; The inside of described tensioner case is provided with expansion tightening wheel; Described expansion tightening wheel is connected with tensioner case by the anchor shaft of its both sides; On described expansion tightening wheel, be provided with the draw-in groove that allows flexible steel wire pass through; The both sides of described main box are provided with mounting hole; The inside of described main box is provided with counterweight chamber; Described counterweight chamber is connected with tensioner case; The bottom of described main box is provided with limit switch and limiting device; Described limit switch and limiting device electrical connection.
Further, in described counterweight chamber, be provided with some mobilizable clump weights.
Further, on described main box, be provided with the buckle that prevents that tensioner case from departing from.
Usefulness of the present utility model is: simple in structure, easy to use, ensure the safety of elevator in the time moving by the use of limiting device and limit switch, and ensure the safety of passenger in elevator.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of expansion tightening wheel.
Fig. 3 is the birds-eye view of expansion tightening wheel.
Wherein: 1-tensioner case, 2-guide rail, 3-main box, 4-counterweight chamber, 5-limit switch, 6-limiting device, 7-mounting hole, 8-anchor shaft, 9-expansion tightening wheel, 10-draw-in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of embodiment of the present utility model is made to brief description.
As a kind of elevator wire rope swelling device of Fig. 1 to Fig. 3, comprise tensioner case 1 and main box 3, the both sides of described tensioner case 1 are provided with for its guide rail 2 sliding up and down on main box 3; The inside of described tensioner case 1 is provided with expansion tightening wheel 9; Described expansion tightening wheel 9 is connected with tensioner case 1 by the anchor shaft 8 of its both sides; On described expansion tightening wheel 9, be provided with the draw-in groove 10 that allows flexible steel wire pass through; The both sides of described main box 3 are provided with mounting hole 7; The inside of described main box 3 is provided with counterweight chamber 4; Described counterweight chamber 4 is connected with tensioner case 1; The bottom of described main box 3 is provided with limit switch 5 and limiting device 6; Described limit switch 5 and limiting device 6 are electrically connected; In described counterweight chamber 4, be provided with some mobilizable clump weights; On described main box 3, be provided with the buckle that prevents that tensioner case 1 from departing from.
The working process of this example: in the time that use is of the present utility model, first, in the expansion tightening wheel 9 of steel wire from tensioner case 1, pass, fixation with steel wire is on the draw-in groove 10 of expansion tightening wheel 9, then, in the time of elevator work, steel rope is tightened up, tensioner case 1 is moved up along main box 3 by guide rail 2, now, limit switch 5 separates with counterweight chamber 4, elevator is normally worked, finally, in the time there is fracture in steel rope, counterweight chamber 4 is past whereabouts under the effect of gravity, in the time that counterweight chamber 4 and limit switch 5 contact, limiting device 6 is started working, now elevator will be fixed on existing position and quit work.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
